Micron-compatible DDR4 ECC RDIMM

This 16 GB DDR4 module runs at 2933 MT/s with a CL21 latency and operates at 1.20 V. It is a registered single-rank 1Rx4 design built for Micron MTA18ASF2G72PZ-2G9 platforms. The 288-pin RDIMM form factor fits server and workstation motherboards that require ECC registered memory.

Sustained throughput with error correction

Registered buffering and ECC keep data integrity intact during long compute runs and virtualised workloads. The 1Rx4 organisation delivers consistent bandwidth without the variability seen in unbuffered consumer modules. CL21 timing supports stable operation across extended sessions in multi-socket environments.

Low-voltage operation without a heat spreader

At 1.20 V the module draws minimal power and runs cool in densely populated DIMM slots. The absence of a heat spreader reduces height for tight chassis clearances while passive airflow handles thermal load. Silent operation is maintained in rackmount and tower servers alike.

Questions about this item

How much heat and power does this 1.20 V DDR4 2933 ECC RDIMM add when the server runs continuously?

The module operates at 1.20 V with no heat spreader, so it adds minimal thermal load and draws standard DDR4 power for a 16 GB registered DIMM.

What must the motherboard already provide for this 288-pin registered DIMM to function?

The board needs a DDR4 RDIMM slot, support for ECC registered memory, and a memory controller that can run at 2933 MT/s with CL21 timing.

Will this 1Rx4 CL21 module work alongside older DDR4 ECC RDIMMs of different ranks or speeds?

It can run in the same channel as other DDR4 ECC RDIMMs, but the system will clock all modules to the lowest common speed and timings; mixing ranks is supported by most server chipsets.
